Abstract: 1,179,056. Data transmission. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 April, 1968 [8 April, 1967], No. 16539/68. Heading H4P. A transmitter for binary pulse signals comprises a binary pulse source 1 whose pulse instants coincide with equidistant sequential clock pulses, and a coding device incorporating a feedback shift register 4, the shift register input being derived from a first modulo-2 adder 11 receiving pulses from the source and the feedback loop, and the latter being derived from a further modulo-2 adder 13 receiving pulses delayed by integral numbers of clock periods and which are derived from the outputs of certain shift register elements. A prescribed transfer function of the transmitter is obtained by interconnecting the outputs of the shift register elements through respective attenuation networks 15-21 to a summation device 22 from which the output signal of the transmitter is derived. The shift period is a sub-multiple of the clock period, and a pulse regenerator 25 controlled by the clock pulses may be inserted between the first modulo-2 adder 11 and the shift register input to ensure that the input feedback signal includes pulses solely of clock period duration. A mathematical analysis is included. Specification 1,044,412 is referred to.

Title: An improved method and machine for packing cigarettes and similar stick-like articles
IPC: B65B19/22
Filed: 1950-07-04
Abstract: 688,931. Wrapping machines. KÍRBER, K. July 4, 1950 [July 12, 1949], No. 16628/-50. Class 94(i) A batch of cigarettes or like rod-shaped articles is wrapped to form a block-ended package while being moved continuously in a circular path. The machine shown comprises a circular channel 1, six arms 3a-f rotated by a shaft 2 and carrying pivoted fingers 5 projecting into the channel and coupled by linkage 6 to rollers 7 engaging a cam 8, and six arms 4a-d pivoted at 9 to a hub on the shaft. Each arm 4 is urged by a spring towards the channel and carries a roller 10 engaging a cam 11, and grippers 12 which are mounted on a rotatable and radially-slidable member urged by a spring 13 against a stop 14 connected by a slidable rod 15 to a roller 16 adapted to engage a cam 17, the grippers being so mounted as to be opened and closed when the member is moved outwardly and inwardly. The member is rotatable by the engagement of a roller 18 thereon with fixed members 19 and 20. Each finger 5 engages a batch of cigarettes fed downwardly through a hopper 36 and carries it into engagement with a wrapper 21 which has been fed across the channel from a roll 22 and cut off by knives 23, the wrapper being thereby folded into U-shape about the batch. The side portions of the wrapper are folded and seamed in known manner at station 24, a second, outer wrapper 27 is applied in a similar manner and its sides folded and seamed at stations 30, 31, and the partiallyformed package is conveyed through the channel until the roller 7 moves into a depression in the cam 8 and the finger 5 is withdrawn. Simultaneously, the roller 10 moves on to a low portion of the cam 11 and the roller 16 engages the cam 17 to move the grippers 12 inwardly and cause them to close on to the package. The roller 18 then engages the member 19 to rotate the grippers through 90 degrees, the roller 16 rides off the cam 17, thereby opening the grippers, and the roller 7 moves out of the depression to swing the finger 5 back into the channel. The grippers are subsequently rotated a further 90 degrees into their original position by the engagement of the roller 18 with the member 20. The finger 5 moves the partially-formed package into engagement with end-tucking, folding and securing devices 33 of known construction and the completed package is transferred by an arm 34 on to a discharge conveyer 35.

Title: Directional control valves
IPC: F15B13/04
Filed: 1973-04-06
Abstract: 1425602 Valves PARKER-HANNIFIN CORP 6 April 1973 [5 May 1972] 16632/73 Heading F2V A directional control valve for controlling two fluid motors has a pressure compensating piston 42 which, by by-passing any excess fluid, maintains a constant flow rate to the selected motor and in the event that both motors are selected for operation it provides for constant flow in the motor subject to the greater load. Fluid supply, via passage 43, is controlled by two spools 40, 41 the openings 59 in which are uncovered by the required amount to supply respective motors 50, 51 as the spools are displaced to the left or right from the neutral position shown and as fluid pressure operates secondary compensating pistons 60, 60 to uncover the orifices 61 in the spools 40, 41. At the same time check valves 62, 62 are unseated to permit pressure to be fed to the pressure compensating piston 42 via orifices 63 in the spool, passage 52 and restriction 53. Inlet pressure is fed to the chamber 57 at the other end of the pressure compensating piston via orifices 64 and 56 and the piston moves to a position to by-pass any excess flow so to maintain a constant pressure differential between the inlet pressure and that existing in the motor feed passage, i.e. to maintain a constant flow in accordance with the setting of the spool. If both motors are selected for operation the higher of the two pressures within the spool passages 68 will close the other check valve 62 to maintain the pressure in the chamber 54 of the pressure compensating piston at this higher level thus providing by-passing action in accordance with the flow to the more highly loaded motor and allowing the higher pressure to act on the secondary compressing piston 60 to control the flow to the corresponding motor. When both spools are in neutral, pressure in chamber 54 leaks away to exhaust via restrictions 53 and 58 and the piston 42 moves over to the right to provide maximum by-pass action, thus unloading the pump. Should pressure in chamber 54 becomes excessive under operating conditions valve 69 opens to provide an exhaust connection which causes piston 42 to provide an immediate relief action, restriction 53 preventing a build up of pressure in the chamber while valve 69 is open. In another embodiment, Fig. 3 (not shown), the fluid pressure for operating the pressure compensating piston (42<SP>1</SP>) is riot taken via the interconnecting passage 52 of Fig. 2 but via a check valve (78) in each spool giving access to the pressure in the axial bore of the spool upstream of the secondary compensating piston.

Filed: 1972-04-14
Abstract: 1389615 Foam generators H E WRIGHT 14 April 1972 17318/72 Heading B1C [Also in Divisions B8 and F1] A foam producer and dispenser, Fig. 3, comprises a reservoir containing air space and a foamable liquid space, foam producing means 30 having a mixing chamber 42 and a non- porous hollow tubular element 38 extending between the chamber and the liquid space, one or more restricted air passages 58 placing the chamber in communication with the air space, and a discharge orifice 26, the reservoir having a wall 12 which is deformable to reduce the reservoir space and increase the air pressure to displace the liquid and air to the chamber, effect intermixing and discharge of the foam produced. To place the discharge orifice 26 in communication with the chamber 42 the cap 22 containing the orifice is partially unscrewed to disengage bevelled surfaces 54, 56. To increase the air pressure, the reservoir, which is made for example of polyethylene is compressed, the pressure causing the air to pass through the passages 58 and liquid to pass up past a non-return ball valve 60 into the mixing chamber 42; for optimum foaming, a porous homogenising element 64 is provided above the mixing chamber. Instead of providing air passages 58, the wall surrounding the mixing chamber may be porous. A distributor, Fig. 9 (not shown) may be attached to, or formed integrally with, the discharge orifice 26. In Fig. 8, the air pressure may be supplied by a compressible bag 118 instead of the deformable wall 12 to cause air to enter the mixing chamber 149 through passages 147 and to enter a secondary mixing chamber 134 through a passage 136, the passages 147 being disposed above the level of the liquid in the reservoir 12; a homogenising element 128 is also provided. In Fig. 10, the homogenising element 64' serves as an air flow valve and is movable to an upper position during a dispensing operation and to a rest position on projections 67 to allow air to pass inwardly through the passage 26 into the reservoir. In embodiments illustrated in Figs. 6 and 7 (not shown) the liquid is stored in one or two bags disposed within the reservoir. In another embodiment, Fig. 12 (not shown), the foam producing means is normally urged upwardly into sealing engagement by a compression spring 184; when the compressive forces from the reservoir are released, the pressure differential acts downwardly to allow air to pass into the reservoir.
